计算餐补（go语言实现）

最近公司需要每月计算餐补（按工作日，每日15元），然后自己去弄发票。

遂写个程序帮助自己计算工作日和这个月的全勤餐补。

程序如下（公司的年假比国家的长，所以如果和我不是一家公司的话需要复用还需要自行修改holiday和specialday数组）。

package main

import (
"os"
"fmt"
"time"
"strconv"
)

func PrintUsage(){
fmt.Println("Usage:./calMoney [month]. Exp: ./calMoney 2 ")
}

func calDays(curYear int64,curMonth int64) int64{
if curMonth != 2{
if curMonth == 4 || curMonth == 6 || curMonth == 9 || curMonth == 11{
return 30
}else{
return 31
}
}else{
if (curYear%4 == 0 && curYear%100 != 0) || curYear%400 == 0 {
return 29
}else{
return 28
}
}
}

func isHoliday(curDate string) bool{
//是2016年的节假日，其他年份需要相应调整
var holiday []string = []string{
"01-01","01-02","01-03",
"02-03","02-04","02-05","02-06","02-07","02-08","02-09","02-10","02-11","02-12","02-13","02-14",
"04-04","04-05","04-06",
"05-01","05-02","05-03",
"06-09","06-10","06-11",
"09-15","09-16","09-17",
"10-01","10-02","10-03","10-04","10-05","10-06","10-07",}
for _,curHoliday := range holiday{
if curHoliday == curDate{
return true
}
}
return false
}

func isSpecialday(curDate string) bool{
//是2016年的调休【即星期六星期天需要上班的日子】，其他年份需要相应调整
var specialday []string = []string{
"06-12","09-18","10-08","10-09",}
for _,curSpecialDay := range specialday{
if curSpecialDay == curDate{
return true
}
}
return false
}

func CalMoney(curYear int64,curMonth int64){
dayOfMonth := calDays(curYear,curMonth)
workDay := 0

var curDay int64

for curDay=1; curDay<=dayOfMonth; curDay++{
var curTimeStr string
if curMonth < 10{
if curDay < 10{
curTimeStr = fmt.Sprintf("%d-0%d-0%d 00:00:00",curYear,curMonth,curDay)
}else{
curTimeStr = fmt.Sprintf("%d-0%d-%d 00:00:00",curYear,curMonth,curDay)
}

}else{
if curDay < 10{
curTimeStr = fmt.Sprintf("%d-%d-0%d 00:00:00",curYear,curMonth,curDay)
}else{
curTimeStr = fmt.Sprintf("%d-%d-%d 00:00:00",curYear,curMonth,curDay)
}
}
loc, _ := time.LoadLocation("Local")
curTime,_ := time.ParseInLocation("2006-01-02 15:04:05",curTimeStr,loc)

if ((curTime.Weekday() == time.Saturday || curTime.Weekday() == time.Sunday) && !isSpecialday(curTimeStr[5:10])) || isHoliday(curTimeStr[5:10]){
continue
}else{
fmt.Println(curTimeStr[0:10])
}

workDay += 1
}

//餐补一天15元
moneyOfDay := 15
//当月餐补
fmt.Printf("total money:%d\n",workDay*moneyOfDay)
}

func main(){
var curYear int64 = 2016

if len(os.Args) != 2 {
PrintUsage()
return
}

curMonth,err := strconv.ParseInt(os.Args[1],10,64)
if err != nil {
PrintUsage()
return
}

CalMoney(curYear,curMonth)
}

运行效果如下：



2月份的工作日和餐补如截图所示。
